Interbus with TSX Momentum
1.1
General Interbus Information
Interbus is an open communications standard currently supported by over 200
equipment manufacturers offering a wide spectrum of diverse products. The
Interbus is a high–speed network designed to couple I/O modules, sensors,
actuators, and control devices with PLC’s and large–scale computer systems.
Interbus operates as a master/slave network, optimized for efficient I/O data
exchange. It can support up to 256 nodes over a distance of roughly 13 km using
twisted–pair cabling, and is able to read 1024 inputs and write 1024 outputs within
4 ms. It thus offers an optimum of control device configuration flexibility with
respect to the number of drop stations and transmission distances. In spite of it’s
extraordinary configuration flexibility, the Interbus makes no compromises in
regard to system performance or I/O data reliability. As a result of the open system
architecture, TIO and Momentum I/O modules can be cost–effectively integrated
into a control system with ease, together with Interbus–compatible products of
other manufacturers. Such a typical system configuration with TIO and Momentum
I/O modules is shown in
Figure 1 (page 10).
The 170 INT 120 00 Interbus communications adapter forms the communication
interface between the I/O bases and the Interbus network. It can be plugged
directly into any Momentum I/O base, with which it then forms a fully functional I/O
module on the Interbus.

170 INT 120 00 Communications Adapter Basics
1.2.1
Environmental Conditions
The communications adapter’s environmental specification conforms to that of the
I/O bases upon which it can be mounted. Specifics can be found within the system
data presented in the 870 USE 002 02 User Manual for TSX Momentum I/O
Bases.
1.2.2
Communications Adapter Installation
The communications adapter (executed in the IP20 safety classification) connects
to the I/O base through a single connector. The adapter is locked firmly in place by
spring clips, and can be easily removed with a screwdriver.
A label inlay is supplied with the I/O base and fits directly into the recessed area at
the front of the adapter. The signal names given to the connected sensors and
actuators can be identified directly upon the label. A small opening at the right side
of the label inlay keeps the bus adapter’s name visible.
1.2.3
Function
The bus adapter is equipped with 2 Interbus ports (incoming and outgoing remote
bus) for fiber optic cable conforming to the Interbus standards DIN 19258.
Each Interbus node updates & regenerates the incoming message stream before
passing it on to the next node. Message handling includes the extraction of output
data destined for the adapters host I/O base, and the addition of any collected
input data.
1.2.4
Error Control Procedures
The internal power supply (Vcc) required by the adapter is provided by the host
I/O base. Vcc is monitored, generating a reset signal whenever Vcc is out of
tolerance.
The INT 120 00 also performs quality monitoring of the optical transmission
medium. The light level at the incoming and outgoing remote bus optical receivers
is measured and compared with a preset threshold value. Any lesser values are
20

Height: 216 mm

Interbus with TSX Momentum
reported to the master. This condition is visually signalled through the status LEDs
(WG, WR), also refer to to the LED status displays table (page 22).
Any I/O error reported by an I/O base is sent as a module error to the bus master
through the Interbus.
1.2.5
Light Level Test Function
The ”Test” push–button can verify optical transmission quality without the need for
an additional measuring instrument. With the Interbus properly installed, a press of
the push–button starts testing. This causes the incoming light level to be
registered and qualitatively evaluated. If neither the WR nor the WG status LED
lights when the push–button is pressed, then the incoming light level is at least
–22 dBm.
Possible causes if either the WR or WG status LED should light when the
push–button is pressed:
8
H
The transmission path is too long –> select another type of medium/adapter,
or make use of a repeater
H
The bending radius is too small –> choose a larger radius
H
Bad connector quality, dirty lens (needs cleaning), or fiber end scratched
(polish)
H
Broken fiber

1.3
Interbus Configuration with TSX Momentum
A brief summary of Interbus topology and configuration follows:
The Interbus is composed of both remote and peripheral bus segments. All bus
segments convey the same signals, but make use of different electrical levels.
Remote Bus
The remote bus supports data transmission over long distances (refer to the
Technical Specifications). The first remote bus segment starts at the Interbus bus
master. The remote bus cable does not carry a supply voltage, and operates
full–duplex at 500 Kbps. Typical remote bus nodes are Momentum I/O modules,
TIO modules, or bus taps. The portions between two remote bus nodes are
referred to as remote bus ”segments”.
Local Remote Bus The local remote bus is derived from a bus tap (e.g. 170 BNO 681 00, or 170
BNO 671 00). The bus tap is itself a remote bus node in the Interbus network.
The Momentum I/O modules on the local remote bus are the same as those for
the remote bus.
Field Bus
The field bus is derived from special bus taps. The bus tap is itself a remote bus
node. The field bus I/O modules are special, and cannot be utilized on the
remote bus.
Note
References to IP 65 modules can be found in the 870 USE 100 02 manual
(170 ENO 396 00, 170 EDI 346 00, and 170 EDO 346 00)
Note
TSX Momentum I/O modules may only be employed with the remote bus and local
remote bus. This does include the field bus, but not the previously mentioned
peripheral bus.

Two commercially available converters are available for the transition from fiber
optic cable <–> RS–485:

I/O Words and ID Code
The first bus adapter action after power–up is to automatically read the I/O base’s
ID code. The ID code provides the Interbus master with the I/O base type (inputs
or/and outputs) and the number of words it requires in the Interbus message.
Once the Interbus master has obtained and evaluated the ID codes of all the I/O
modules, it automatically begins with the exchange of data in real time.
Lengths are expressed in I– (input) or O– words (output); with the higher number
being the decisive factor as to the number of words required within the Interbus
message. The following value set can be seen: 1 ... 10, 12, 14, 16, 24, or 32
words.
Example
The ID code for the 170 ADM 350 10 is hex 0103.

H
01 = length means: the module requires one word (I– or/and O–word)

Register Mapping for I/O Bases
2.2.1
Addressing for Discrete I/O Bases
Addressing is according to IEC. Data exchange between the I/O base and
communications adapter takes place 1 : 1.
The I/O points at the periphery terminals of the discrete TSX Momentum modules
are mapped according to the following principles:
H
H
H
H
Values are always mapped to full words (max. of 2 for 32 inputs or 32
outputs).
The higher value word (MSW) is the first to be sent or received.
Those words sent to the I/O base (output words) from the communications
adapter represent the output values and parameters.
Words sent to the communications adapter (input words) from the I/O base
represent input values and statuses.
An example of register mapping for two discrete I/O bases is shown:
Register mapping for the 170 ADI 350 00 (32 inputs) and 170 ADO 350 00
(32 outputs)
170 ADI 350 00 input data

170 BNO 681 00 Bus Tap General Specifications
The connections to the incoming power supply, relay output connection, and a
reconfiguration push–button are made through an 8–pole terminal block connector.
The terminal block is available in screw–in and spring tension terminal styles.
Below the type identifier is the single–colored function designation marking:

170 BNO 681 00 Module Description
4.2
Mechanical Design
The modules have a flat plastic housing that can be affixed on a DIN mounting rail,
or be fastened with only 2 screws to a wall or machine housing. The housing is
narrower than the other Momentum modules. With the mounting rail installation
additional fixation measures are unnecessary, as a stopper mounted in the
housing back panel prevents sideward slippage. A spring integrated in the back
panel accomplishes the electrical grounding to the mounting rail.
There are ventilation slits above and below the identification inlay, so that sufficient
natural cooling convection is provided for vertical mounting.
The following diagnostic and status LEDs are located in the slits below the
identification inlay (for the position and significance refer to Figure 4 ”170 BNO
681 00 status LEDs”):
H
1 LED shows the state of the relay output (REL)
H
5 LEDs for bus diagnosis (BA, RC, RD, LD, E)
H
1 LED for power monitoring (ready)
H
2 LEDs indicating light level (WR, WG)
The device can be exchanged simply on failure, as the cabled terminal strips can
be unplugged without tools. The identification inlay can be easily loosened with a
screwdriver and exchanged to the replacement device.
Note
The 170 BNO 681 00 fulfills the IP20 safety class specifications. These modules
must be installed in closed service cabinets within electrical equipment bays.
During work on the service cabinets the user must follow the appropriate
maintenance precautions to prevent module damage through electrostatic
discharge.

Function
4.3
The 170 BNO 681 00 bus tap possesses the following hardware functions:
4.3.1
Power Supply
The supply voltage amounts to UB = 24 VDC. The logic supply
(VCC = 5 VDC) is derived from the 24 VDC and is monitored. A green LED
(ready) lights while the voltage is within the tolerance range. A reset is initiated
when the voltage falls out of tolerance.
4.3.2
Bus Interfaces
The module is equipped with three Interbus interfaces. The incoming and outgoing
interfaces are conceived for the connection of fiber optic cable. The local remote
bus is connected through a Sub–D9 plug. This port is suitable for OPTOSUB use.
A slide switch tells the BNO if it is the last remote bus node.
”NEXT”
”END”
4.3.3
Additional nodes follow
Last node
8–Pole Terminal Block
The terminal block carries a connection to a reconfiguration push–button with
which the local remote bus can be reset. In addition a relay output is present which
can signal a local remote bus failure (the relay has a change–over contact
assembly).

170 BNO 681 00 Module Description
During cabling the following protective measures must be observed:
34
H
Fuses should be dimensioned appropriately for the connected consumers.
H
For large loads, particularly inductive loads, the relay output contacts must
be provided with appropriate, directly adjacent installed, suppressor circuitry
(RC-network, varistor, or a clamping diode for DC).
H
Up to two 2.2 nF to PE per contact may be necessary for supression. This is
of course dependent upon the degree of environmental disturbance
encountered (7 capacitors of this type reside in the ”GND 001” capacitive
by–pass terminal for A120 accessories).
H
The reconfiguration request input is not isolated from the VCC logic voltage
and hence only conceived for use with push–buttons.
